Es wird vorgeschlagen, dass die Matrix (12) nach Durchführung des Pultrusionsverfahrens mindestens teilweise aufgeschäumt wird.The invention relates to a method for producing at least one fiber-reinforced plastic profile (10) by pultrusion on the basis of a thermoplastic matrix (12) with fibers (14) impregnated in the matrix (12). It is proposed that the matrix (12) is at least partially foamed after carrying out the pultrusion process.
Description
Die Erfindung betrifft ein Verfahren zur Herstellung mindestens eines faserverstärkten Kunststoffprofiles nach dem Oberbegriff des Anspruchs 1.The The invention relates to a process for producing at least one fiber-reinforced plastic profiles according to the preamble of claim 1.
Aus
der Offenlegungsschrift
Aufgabe der Erfindung ist es, ein einfaches und kostengünstiges Verfahren zur Herstellung von faserverstärkten Kunststoffprofilen bereitzustellen, das eine Isolierung der faserverstärkten Kunststoffprofile bereits im Fertigungsprozess ermöglicht.task The invention is a simple and inexpensive Process for producing fiber-reinforced plastic profiles to provide an insulation of the fiber reinforced Plastic profiles already possible in the manufacturing process.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.These Task is according to the invention with the features of claim 1.
Bei einem erfindungsgemäßen Verfahren zur Herstellung von faserverstärkten Kunststoffprofilen wird die Matrix nach Durchführung des Pultrusionsverfahrens (auch Strangziehverfahren) mindestens teilweise aufgeschäumt. In vorteilhafter Weise kann der Schaum als Isolierung für das faserverstärkte Kunststoffprofil dienen. Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens liegt darin, dass hierdurch eine Isolierung des faserverstärkten Kunststoffprofils bereits im Fertigungsprozess ermöglicht ist. Hierdurch ist kein zusätzliches Werkzeug und auch kein weiterer Fertigungsschritt notwendig. Somit können bereits bestehende Anlagen zur Durchführung des erfindungsgemäßen Verfahrens verwendet werden, da die Anlagen ohne Umbauten dafür eingesetzt werden können. Ein besonderer Vorteil des erfindungsgemäßen Verfahrens liegt darin, dass kein zusätzlicher und insbesondere kein artfremder Werkstoff zur Isolierung notwendig ist, so dass eine verbesserte Recyclingfähigkeit des Kunststoffprofils erzielt wird. In vorteilhafter weise ist der Schaumstoff praktisch aus jedem Kunststoff herstellbar.at a process according to the invention for the preparation of fiber reinforced plastic profiles becomes the matrix after carrying out the pultrusion process (also pultrusion process) foamed at least partially. In an advantageous way The foam can be used as insulation for the fiber-reinforced plastic profile serve. A significant advantage of the invention Procedure is that this results in an isolation of the fiber-reinforced Plastic profiles already in the manufacturing process is possible. This is no additional tool and no further production step necessary. Thus already can existing systems for carrying out the inventive Procedure used because the equipment used without any modifications can be. A particular advantage of the invention Procedure is that no additional and in particular no kind of foreign material is necessary for insulation, so that achieved an improved recyclability of the plastic profile becomes. Advantageously, the foam is virtually of any kind Plastic can be produced.
Vorzugsweise erfolgt das mindestens teilweise Aufschäumen der Matrix durch ein chemisches Treibverfahren. Hierdurch ist auf einfache und kostengünstige Weise ein Aufschäumen der Matrix realisierbar, indem der Matrix nach der Pultrusion mindestens ein Treibmittel zugesetzt wird, wobei die die Matrix aufschäumenden Gase bei der Polymerisation frei werden.Preferably the at least partial foaming of the matrix takes place by a chemical blowing process. This is easy on and cost-effective way of foaming the matrix feasible by at least one of the matrix after pultrusion Propellant is added, wherein the foaming the matrix Gases are released during the polymerization.
Bevorzugt erfolgt das mindestens teilweise Aufschäumen der Matrix durch ein physikalisches Treibverfahren. Auch hierdurch ist auf einfache und kostengünstige Weise ein Aufschäumen der Matrix realisierbar, indem in der Matrix mindestens ein Gas zur Expansion gebracht wird. Hierbei werden der Matrix nach der Pultrusion niedrig siedende Flüssigkeiten zugesetzt, die im Verlauf der Polymerisation verdampfen und so die typischen Gasblasen bilden.Prefers the at least partial foaming of the matrix takes place by a physical blowing process. This, too, is up a simple and inexpensive way of foaming The matrix can be realized by at least one gas in the matrix Expansion is brought. This will be the matrix after pultrusion low-boiling liquids added in the course evaporate the polymerization and thus form the typical gas bubbles.
In einer vorteilhaften Ausgestaltung erfolgt das mindestens teilweise Aufschäumen der Matrix durch ein Mischverfahren, indem der Matrix mindestens ein Schäumungsmittel zugesetzt und der entstehende Schaum verfestigt wird.In an advantageous embodiment, the at least partially Foaming the matrix by a mixing process by at least one foaming agent is added to the matrix and the resulting foam is solidified.
In einer weiteren vorteilhaften Ausgestaltung erfolgt das mindestens teilweise Aufschäumen der Matrix durch eine Lösungsmethode, indem aus der Matrix nach der Pultrusion Salze unter Bildung von Hohlräumen herausgelöst werden.In a further advantageous embodiment, the at least partially foaming the matrix by a solution method, from the matrix after pultrusion salts to form cavities be removed.
Vorzugsweise handelt es sich bei dem faserverstärkten Kunststoffprofil um einen Tank eines Warmwasserspeichers. In vorteilhafter Weise kann hierdurch der Warmwasserspeichertank bereits bei seiner Fertigung mit einer Isolierung versehen werden, so dass sich eine deutliche Kostenersparnis bei der Herstellung ergibt.Preferably it is the fiber-reinforced plastic profile around a tank of a hot water tank. In an advantageous way This allows the hot water storage tank already during its production be provided with an insulation, so that a clear Cost savings in the production results.
